applicable drawings, specifications, procedures,. codes, regu* story requirements and documented instructions relating to soils inspection at the construction site.

i 2.0 SCOPE i

The scope of the procedure applies to safety-related items and services involving excavation and backfill operations. The soils control activities will be performed in the excavated areas, borrow-stockpile wl areas, the plant backfill and earch, structure backfill areas. In-place inspections and costs as well as laboratory tests and analyses will be performed as a combined program for control of intergrated activities in all areas.

sa m'

l The scope of inspection activities shall be divided into two types of inspection, full scale Q. C. inspection of soils operations when E

Ebasco Services, Inc. is doing the work and random inspection when others are doing the work.

~ All soils placements, inspection and testing operations shall be conducted in accordance with the drawings and specifications.

Inspections results shall be recorded on Form QCIP-2-3 for each shift by each inspector and shall include the following:

6.4.1 Material has been determined to be suitable and released for backfill.

6.4.2 Base to receive backfill has been properly prepared W

and compacted to the density required.

6.4.'3 Backfilling is accomplished in the proper sequence d

in accor, dance with Ebasco Drawing No. LOU-1564-G490.

6.4.4 Sand backfill materials for Class "A" fill are spread y

and leveled in layers not exceeding 15 inches prior to compaction, e

g 6.4.5 Clay for Class "A" backfill and material selected from g3 the excavation for Class "B" backfill is placed in layers not exceeding ten inches prior to compaction,

=

y g

6.4.6 Fill material is deposited uniformly over entire area being filled to a particular stage or level, we h

6.4.7 When required, fill material shall be disc-harrowed after spreading and before compaccion to blend and aerate the material into a texture that can be consolidated 2

into a homogeneous mass by the compaction operations.

g 6.4.8 Surface of each lift is kept reasonably smooth and free of ridges or grooves which would adversely affect proper

,g compaction of subsequent lifts.

e 6.4.9 Hauling equipment uses paths different from each other in order to aid compaction of the entire area and to

,g

c. void overcompaction of any given area.

E 6.4.10 If area to receive fill is an original excavation, or h

compacted more than two days previously, surface shall be cleaned of all loose debris and improperly compacted material. Area then shall be proof rolled and accepted prior to subsequent backfill.

6.4.11 When two sections of fill join, fill placed first must have its slope shaved a minimum of three feet to expose undisturbed compacted material.

6.4.12 Compaccion'is achieved with proper equipment operatin'g and proper speed.
